I found a number of "Preparing Your Canvas" posts in the LMS Migration Strategies group hub. Do you have links saved so that you can provide us with links to the ones that you haven't been able to find here?
This is the "tying it all up" post you created a while back.
I checked all the posts, and the only two that work are for "Tying it all up" and "The Feather of Truth" Every other post is unavailable:
Thanks for your patience! I was able to locate and move all of the posts listed except for the last one ("Coda") and the links should now work.
Oh, thank you! Finding those means a lot to me.
It's our pleasure, and thank you for all the work you've done creating and sharing awesome content with the Canvas Community as a whole. Please let us know whenever you need assistance finding errant links.
